record.getUserIdentity()

[guilhermecvm]

Hi, trying to convert DynamodbEvent to List<Record>, however when the lambda gets excuted, seems like record.getUserIdentity() returns null, therefore breaking toIdentityV2. Is it the case that the user identity is nullable and a safety check is needed?

fun handleRequest(event: DynamodbEvent, context: Context) {
  DynamodbEventTransformer.toRecordsV2(event)
}

java.lang.NullPointerException

The fix for this was released as part of aws-lambda-java-events-sdk-transformer version 2.0.6 and is now available through Maven https://search.maven.org/artifact/com.amazonaws/aws-lambda-java-events-sdk-transformer/2.0.6/jar

Thanks again!
